A psychological disease where you think you are in love but you're not and you say you're not together but you are. You can't help but be in denial with all your friends and family otherwise you may vomit, faint and even die.

"There's no point in telling her she's suffering from Retoni. She's just going to deny it and if I hear a story about how they're NOT together one more time... I might vomit or even worse- catch it."
